2.2.1 DUO-CEL control board
2.2.2 Display overlay and insert
The DUO-CEL panel is available in two formats;
Standard and Twin-Wire. The standard panel
monitors conventional detectors on the zone
circuits and operates conventional sounders via the
sounder circuits. The twin-wire panel monitors
conventional detectors on the zone circuits but can
also operate Fulleon Twin-Wire sounders from the
zone circuits. The conventional sounder circuits are
still available on the twin-wire panel.
The Twin-Wire control board is slightly different to
the Standard control board but this is only evident
at component level. Both control boards consist of a
PCB with all components mounted on the front. All
LED indicators, configuration switches/links and
user controls are mounted on this board. The board
accommodates the microcontroller (including
Firmware and RAM) and all of the site-specific
configuration features (DIL switch & EEPROM).
Power supply monitoring circuitry is also located on
this PCB.
The display overlay is bonded to the PCB cover
and is used with a text label insert to identify each
of the zones. The insert slides into a pocket in the
overlay and cannot be removed when the front
cover is fitted.
User controls are operated by pressing on the
rectangular printed buttons on the overlay,
providing mechanical contact with the buttons on
the PCB.
The LEDs on the PCB are viewed through oval
windows in the overlay.
The text on the overlay is printed and therefore any
language variants will require replacement of the
complete overlay on the PCB cover.
The zone location insert is a card allowing text to be
hand-written or typed. It is not compatible with
printers. A paper insert can be used if printing via a
computer is required (paper insert is not supplied).

NOTE: The battery clamp is not designed to clamp
batteries other than the PS-1230.
2.2.3 Power Supply
The Power Supply is a self-contained switch-mode
unit and is mounted underneath the control board.
This unit provides 27.5VDC (nominal) at 1.5A to the
control board.
The output from the PSU is temperature
compensated, i.e. the battery charging voltage is
automatically adjusted to the safest optimum value
depending on the temperature of the batteries.
The PSU is connected to the control board by two
leads:
2.2.4 Repeater Panel
The repeater panel uses the same control board
and enclosure as the fire alarm panel. The
components for the redundant circuits [zones,
alarm circuits etc] are not present on the repeater
control board. The repeater and fire panel
mechanical arrangements are similar. The repeater
can be supplied with its own battery-backed
230VAC PSU, or without a PSU (powered directly
from the Fire Alarm panel‟s Auxiliary DC output).
Repeaters are only supported on the 4-zone & 8zone panels.
Up to 3 repeaters can be connected to the panel.
The panel controls the Repeaters through the
RS485 serial communications link.
The output lead has a 3-way socket, providing
0V, 28V and Mains Fault signals. (The
connector on the panel motherboard may
th
have a 4 pin for Functional Earth connection
from alternative power supplies).
The Thermistor lead connects to the
Thermistor socket on the control board, the
Thermistor being situated on the control
board. (The Thermistor is used to monitor the
battery temperature).
The control board provides connections for the
standby batteries via spade terminals.
The enclosure accommodates 2-off 12V 3.4Ah
Sealed Lead-Acid Powersonic PS-1230 batteries.

14 x 20mm Gland knockouts at the top.
Temperature-compensated
battery charging
Battery charging voltage is automatically adjusted between 28.25Vdc and
26.72Vdc over an ambient temperature range of –5°C to +40°C.
Battery disconnect
Prevents permanent damage to the battery due to deep discharge by
automatically disconnecting it when the battery voltage falls below 21.6V.
Remote Control input providing
five controls:
1. Class Change
Operates all sounders for up to 5 seconds without giving any panel
indications.
2. Alert
Pulses all sounders and operates the fire buzzer.
3. Evacuate
Operates all sounders continuously and operates the fire buzzer.
4. Silence Alarms
Latches the Silence Alarms condition until a new alarm condition is
detected or until panel reset.
5. Reset
Returns the panel to the quiescent state after a fault or alarm
condition.
Configurable detection zones
DIL switch configuration provides the following capabilities:
Latching or non-latching Fire indication on zone 1.
Resistor or capacitor EOL monitoring – applies to all zones. (Not
functional on Twin-Wire panels)
Zone Short Circuit gives fault or fire alarm (for backwards
compatibility) – applies to all zones.
Factory configuration:
Latching zone 1 Fire indication
Capacitor EOL (not for twin-wire)
Zone Short circuit gives fault.
Selectable Zonal or General
Alarm Sounder operation
Selectable via DIL switches on the motherboard.
When set to Zonal, the sounders operate as follows:
Twin-wire panels ( 1 to 8 zone):
All 2-wire sounders operate zonally, normal sounder circuits operate
as general alarms

6.1.3 Battery Charger
6. Power Supply
6.1
The power supply is capable of charging 2-off 12V
3.4Ah SLA Powersonic PS-1230 batteries.
The power supply unit monitors a Thermistor on the
panel control board and automatically adjusts the
output voltage to provide the optimum safe
charging voltage over an operating temperature
o
o
range of -5 C to +40 C.
The charging voltage can be adjusted via the
trimmer potentiometer VR1 on the PSU. However,
the charging voltage is factory set and adjustment
should not be necessary (a 15K resistor can be
o
used in place of the Thermistor to simulate 25 C).
General
The DUO-CEL uses a BENTEL BAQ35T24 switch
mode Power Supply which has the following
features:
Input voltage: 230 VAC 50/60Hz
Output voltage: 27.15VDC (nominal @ 25 C)
Stability over 1% with full load
Overload protection
Short-circuit protection
Insulation class 1
Tested and approved to EN 60950:1996 +
A4:1997
Dimensions: 130mm x 100mm x 38mm
o
NOTES:
1. The battery charging voltage is temperature
dependant and should be set as detailed in
Table 2. Charging at too high a voltage may
result in overheating, resulting in damage to
the batteries. Charging at too low a voltage
will result in insufficient charging of the
batteries.
2. The charging profile of the power supply unit
is optimised for Powersonic™ batteries and
charging of other manufacturers’ batteries is
not recommended. Consult your battery
supplier or battery manufacturer before use.
Table 2 – Float Charge Voltages for
Powersonic VRLA batteries
Weight: 389g
The battery monitoring circuit is part of the control
board. This provides:
Thermistor for temperature compensation
Battery/charger fault monitoring
Automatic
“battery
disconnect”
facility.
Disconnects the battery when the battery
terminal voltage falls below 21.6V, to prevent
deep discharge of the batteries if supplying the
panel for an abnormally long period of time.
Ambient
Temperature
6.1.1 Supply Input
The PSU is designed to run from mains voltage at
230Vac +10%, -15%, 50/60Hz. The input is
protected by a 3A 20mm glass fuse. The fuse is
inside the metal cage and is not user-serviceable.
6.1.2 Supply Output
The output from the PSU is 27.15Vdc ±1% at 25°C
with load up to 1.5A. The output is protected by a
6.3A 20mm glass fuse. The fuse is inside the metal
cage and is not user-serviceable.
The output current is shared between the panel
load and battery charging. The battery charging
current is therefore dependent on output current
and will fall to zero as the panel load approaches
1.5A.
The output is connected to the panel via a threewire flying lead, providing the DC power and a failsafe fault signal.

6.1.4 Battery Monitoring
The health of the batteries, the battery connections
and fuse are checked by a battery monitor circuit on
the panel control board.
The batteries are monitored for disconnection. If
the battery voltage falls to 18V or below then a
PSU fault is raised and the charging voltage is
removed from the terminals.
The batteries are monitored for low voltage. If
the battery voltage drops below 21.6V when the
mains power is disconnected, then the batteries
are electronically disconnected to prevent deep
discharge. The batteries are reconnected only
after mains power is restored.
The batteries are monitored periodically for high

internal resistance. A PSU fault will be raised if
high resistance is detected. This test involves
loading the batteries so a battery load test is
also performed.
6.2
Mechanical Protection
Warning:
The power supply uses hazardous voltages.
The unit is fitted with a protective cage to
protect service engineers from electrical shock.
Do not attempt to open or access any of the
internal components. The power supply
contains no user serviceable parts.
To prevent overheating, the ventilation holes in
the cage must not be obscured.
6.1.5 Visual indications
The Power Supply Unit has only one green LED.
This indicates that there is power available on the
output of the power supply.
6.1.6 Fault Conditions
The yellow fault wire from the PSU is normally at
27Vdc (nominal). The panel monitors this signal
and indicates a PSU fault if the voltage is removed.

2. Maximum Cable length is 300m, or 3.63Ω per
core, 63nF core to core & core to screen.
3. The maximum number of detectors and
sounders per zone in section 7.1 assumes no
mixing of devices. The total number of detectors
and/or manual call points per zone must not
exceed 32. This is a recommendation of BS
EN54-2:1997 Annex D. The additional limitations
for twin-wire operation are listed in note (7)
below.
4. The Maximum number of devices per zone is
based
on
factory
default
monitoring
configuration [10uF capacitor EOL for the
standard panel or composite device for the twinwire panel]. For resistor EOL or Twin-Wire, the
total quiescent current drawn per zone by all
devices on the zone should not exceed 1.6mA.
Exceeding this current will result in a failure to
correctly detect an open circuit or head removal.
5. The number in brackets for the twin-wire zone is
the maximum number of devices allowed if NO
twin-wire sounders are connected to the zone.
6. The values are for guidance only and will vary
for individual detectors and cable types. Each
zone must be fully checked for correct operation
& fault monitoring during installation &
commissioning.
7. When using twin-wire sounders, observe the
following additional requirements:
PAGE 16 of 45
a. DO NOT exceed the maximum number of
sounders per zone as listed in the above
table in section 7.1. These figures are based
on extensive testing and allow for operation
EQUIPMENT:
FIRECLASS DUO-CEL

at low battery voltage and no mains power,
on long cable runs.
e. All detector bases must have a 1N4002
diode fitted across the line IN and line OUT
terminals (usually on the positive line but
sometimes on the negative line). Some
detector bases come with Schottky diodes
fitted. These are not compatible with the 2wire zone operation and must be replaced
with 1N4002 diodes. This applies even if no
sounders are connected. Use of a Schottky
diode will prevent the panel from detecting a
detector head removal.
b. When mixing different types of sounders on
the same zone, use the lowest quantity
shown in the table. For example, you can
have 12 SQG3/SDR on a zone as long as no
other sounders are connected on that zone.
If you want to mix SQG3/SDR with SQG3/AV
then the TOTAL number of sounders on the
zone should be limited to 8 (e.g. 7 x
SQG3/SDR and 1 x SQG3/AV).
c. DO NOT leave any detector bases empty. All
bases should have a detector fitted or be
linked through. Empty bases will introduce a
diode into the positive line and this will
adversely affect the operation of the
sounders.
d. Reducing the number of sounders WILL NOT
allow more detectors to be used, unless no
sounders are connected (see number in
brackets in the table).
8. If using detector bases without diodes fitted,
then removal of a detector head will result in an
open circuit of the cable. All devices fitted to the
zone cable beyond the detector head removed
will no longer be powered and will therefore not
operate. Only use detector bases without diodes
if the zone has no 2-wire sounders and no
Manual Call Points, or is configured to Resistor
EOL.

Selection of Zones or Outputs for
Disablement, Enablement or Test
The panel provides a simple and straightforward
means of selecting the sounder outputs and/or
zones which need to be disabled, re-enabled or set
to the test mode. The Fire Signal Output can also
be disabled and enabled or placed into the test
mode.
The zone or output is selected using the Circuit
Select feature. This allows the user to move a
flashing cursor indication down through the yellow
fault LEDs associated with the available circuits
until the required zone or output is highlighted. The
yellow LED for the selected zone/output flashes in
“Cursor” mode, which is easily distinguishable from
all other indications.
For each circuit that the Cursor is on, the General
Test and General Disablement LEDs will indicate
the current status of the circuit; flashing Test
indicates the circuit is in Test mode, flashing
Disablement indicates the circuit is disabled. Both
LEDs OFF indicates the circuit is in normal
operation.
If the circuit is in normal operation, pressing the
Disable button once will disable the circuit,
causing the General Disablement LED to flash
and the circuit fault LED to illuminate steady
(with flashing cursor).
If the circuit is in normal operation, pressing the
Test button once will set the circuit to test mode,
causing the General Test LED to flash and the
circuit fault LED to illuminate steady (with
flashing cursor).
If the circuit is currently disabled, pressing the
Disable button once will restore the circuit to
normal, causing the General Disablement LED
to switch off and the circuit fault LED to switch
off (with flashing cursor).
If the circuit is currently in test, pressing the Test
button once will restore the circuit to normal,
causing the General Test LED to switch off and
the circuit fault LED to switch off (with flashing
cursor).
If the circuit is currently disabled, pressing the
Test button once will change the circuit status
from disabled to test mode, causing the General
Disablement LED to switch off and the General
Test LED to flash.
If the circuit is currently in test, pressing the
Disable button once will change the circuit status
from test mode to disabled, causing the General
Test LED to switch off and the General
Disablement LED to flash.
NOTE: Disablements are stored in EEPROM and
are not lost when the panel is powered down. Test
conditions are cleared when the panel is powered
down.
8.4
Disabled Zones and Outputs
Any or all of the zones can be disabled.
A disabled zone will have power supplied to it but
will not report fire or fault conditions. The zone
power is switched off briefly when the zone is
disabled, and also when the zone is re-enabled.
Detectors on a disabled zone are still able to enter
the alarm condition but will not raise a fire alarm on
the panel.
In the twin-wire mode, sounders on disabled zones
will still be activated during a fire alarm unless the
sounders have been disabled.
The fire panel will respond normally to fire device
operations and wiring faults on all enabled zones.
The following outputs can also be disabled and
enabled:
All Sounder circuits including twin-wire (as a
group operation).
The Fire Signal Output.
A disabled output will not report fault conditions and
will not be activated, although power for monitoring
will still be applied.
8.5
Detector Zone Test.
When selected to the Test mode, devices
connected to the zone can be operated for test
purposes without operating the Fire Signal output or
the Fire Relay.
The zone(s) to be set to the One Man Test
condition are selected using the Cursor Select
feature described in 8.3.
The features of the One Man Zone Test condition
are:
A fire condition on a zone in Test Mode will not
operate any of the fire outputs.
Sounders operate for 5 seconds and then
automatically silence. Sounders operate in
general or zonal mode in accordance with the
panel configuration.
After each test the panel and the device being
tested are automatically reset allowing the next
device to be tested without needing to return to
the panel to silence and reset.
If a fire condition occurs on any zone other
than a zone in test mode, the panel responds
fully to the fire condition as per its normal fire
response and configuration.
8.6
Alarm Sounder One man Test
The One Man Sounder Test operates all sounders
on an intermittent basis until the Test mode is
manually cleared. This allows an engineer to walk
the protected area and confirm the operation of all
the sounders. The sounder on/off cycle is 2
seconds on and 15 seconds off to allow operation

to be confirmed without being too intrusive for other
occupants.
A genuine fire alarm condition overrides the test
mode and operates the sounders normally.
9. Overview of Engineers
Functions
This section provides an overview of the functions
available to the engineer.
9.1
Engineer’s configuration process
On the DUO-CEL panel, most of the Engineer‟s
configuration facilities are controlled by DIL
switches located on the motherboard, accessed by
removing the front cover of the panel. Each
configuration feature has its own dedicated DIL
switch. The DIL switches are as follows:
1: Z1 NON LATCH
2: RESISTOR EOL
3: ALERT MODE
4: DEPEND CONF
5: ZONAL ALARMS
6: S/C FIRE
7: AUX. RESET
8: DISABLE BUZ
9: REP CONFIG
10: SNDR EXPAND (not used)
11: SPARE
12: SPARE
Most functions simply require the appropriate DIL
switch to be either ON or OFF.
The DEPEND CONF DIL switch initiates a
programming mode in which the engineer is able to
select the required zone and set or clear it‟s
dependency mode status. The dependency mode
status is stored in EEPROM and is not lost if the
panel is powered down.
The REP CONFIG DIL switch (not available on the 1
& 2 zone panels) initiates a programming mode in
which the engineer is able to set the number of
repeaters connected to the panel. This data is
stored in EEPROM and is not lost when the panel is
powered down.
On the DUO-CEL repeater, only two DIL switches
are available:
1: NUM REP A
2: NUM REP B
Their setting is shown below:
Repeater No.
NUM REP A
NUM REP B
0 (Disabled)

9.1.1 Zone Dependency selection
When the zone dependency configuration DIL
switch (Depend Conf) is switched to the ON
position, the panel sounds the internal buzzer and
illuminates the SYSTEM FAULT LED to indicate
that the programming mode has been initiated. The
current status of the zones is displayed on the zone
fault LEDs; LED OFF – No Dependency, LED ON –
zone configured for dependency.
Operation of the SELECT button will then switch
the Select cursor on, flashing at the zone 1 fault
LED.
Pressing the Select button again will move the
flashing cursor to the next zone. The cursor will be
switched off after the last zone (1, 2, 4 or 8,
depending on the panel) or if no buttons are
pressed for 30 seconds.
Note that in the Engineer’s programming mode,
any faults, tests or disablements are masked
and are not shown on the display. The panel will
not respond to faults or fires.
With the cursor flashing on the required zone,
pressing the Disable button toggles the state of the
Dependency mode for that zone.
Once all required zones have been configured and
the configuration DIL switch is returned to the OFF
position, the panel will return to normal operation.
Factory default:
All zones are configured for no dependency.
Dependency Details:
This mode of operation conforms to BS EN542:1997 Clause 7.12.1 Type A Dependency.
Operation of an automatic fire detector on a zone
configured to the dependency mode will not
immediately indicate the fire alarm condition on the
panel. A 30-minute counter will be started and the
zone will be held in reset for 5 seconds (no power).
After the zone power is reinstated, if any automatic
fire detector on the same zone operates within 30
minutes, the panel will raise the fire alarm condition.
If no detectors or MCPs are operated on the zone
before the 30-minute timer ends, the zone will
return to coincidence detection (i.e. a detector
alarm on the zone will start the 30-minute timer
again).
Operation of Evacuate MCPs at any time will
always raise a fire alarm immediately.
Operation of an automatic fire detector or MCP on
any zone not configured for dependency will always
raise a fire alarm immediately.
9.1.2 Repeater configuration
When the Repeater configuration DIL switch (REP
CONFIG) is switched to the ON position, the panel
sounds the internal buzzer and illuminates the
SYSTEM FAULT LED to indicate that the
programming mode has been initiated. The current

status of the repeater configuration is also
displayed on the Repeater Fault LEDs, which are
visible when the front cover is removed.
Operation of the Select button will increment the
number of repeaters, up to a maximum of 3, after
which the number is reset to zero.

Once the required quantity of repeaters has been
configured and the configuration DIL switch is
returned to the OFF position, the panel will return to
normal operation.
Factory default: No Repeaters
9.2
Zone 1 Non-latch operation
The Zone 1 non-latch DIL switch allows zone 1 to
be set to non-latching fire indication.
In this mode a fire condition on zone 1 operates the
sounders but not the Auxiliary Fire Relay. The
alarm indication automatically clears when the fire
condition is removed from zone 1, without the need
to manually reset the panel.
9.3
Resistor EOL
The Resistor EOL DIL switch configures all zones
to monitor an end-of-line resistor (6K8 to 3K9)
instead of the default 10uF capacitor. This feature
is not available on the twin-wire panel (i.e. the
switch has no effect).
In the default mode, the panel actively checks for
the presence of a 10uF capacitor at the end of the
zone wiring. Diodes are fitted to detector bases and
removal of a detector will result in a fault condition
being raised at the panel whilst still providing power
to all devices on the zone.
In Resistor EOL mode, the panel monitors the
current drawn by the EOL resistor and indicates a
fault if the current drops below the threshold.
Diodes cannot be fitted to detector bases otherwise
a detector removal could not be detected.
Therefore, a removal of a detector will create an
open circuit and remove power from all devices
beyond the removed detector.
NOTE:
Resistor EOL monitoring is provided for older
installations where it is difficult to change the
EOL resistor to a capacitor.
In addition, detector/MCP discrimination will not
work when the zone monitoring is configured
for Resistor EOL and therefore zone alarm
dependency (coincidence detection) and Alert
Mode will not work correctly.
9.4
Twin Wire
The Twin Wire panels support Fulleon twin-wire
sounders on the zone circuits along with compatible
detectors (see section 7.1).
Each zone can monitor detectors and operate
sounders on the same two wires. The sounders are
activated by pulsing the zone voltage between
11Vdc & 24Vdc (nominal).
The EOL device consists of a Zener diode and
resistor which draws about 4mA in quiescent. A
detector head removal (assuming diode bases are
used) will result in a small voltage drop, which the
panel can monitor & indicate a zone fault.
The zones are also capable of discriminating
between detector and manual call point alarms and
so zone dependency mode is compatible with twinwire panels.
NOTE:
Only TYCO CP211 Manual Call Points can be
used. This is because standard call points will
apply a resistive load and if multiple call points
are operated on a single zone then the load will
be too great to allow the twin-wire sounders to
operate. The CP211 contains current limiting
circuitry such that multiple call points will draw
as much current as a single call point (current
is shared between call points) and will not affect
sounder operation. The CP211 also prevents
excessive loading on the zone when the zone
sounders are operated
9.5
Alert Mode
The Alert Mode DIL switch configures all zones to
discriminate between detector alarms and MCP
alarms. Detector Alarms are treated as Alert, MCP
alarms are treated as Evacuate.
The Sounder circuits are pulsed (1.5 second on, 1.5
second off) during the Alert alarm and operate
continuously during the Evacuate alarm.
When used in conjunction with Zonal Sounder
operation, a detector alarm will only pulse the
relevant zonal sounder circuit with all other sounder
circuits silent. A MCP alarm will operate the
relevant zonal sounder circuit continuously and
pulse all other sounder circuits.
On the display, the left zonal fire LED operates for
MCP alarms, the right zonal fire LED operates for
detector alarms.
NOTE:
Call points should be TYCO CP211 for TwinWire panels. For the standard panels the TYCO
CP211 or a conventional type may be used, but
the MCP resistor needs to be 220R to 360R.
Standard call points with 470R to 680R will be
monitored as a detector alarm instead of a MCP
alarm.
This feature will not work correctly with
Resistor EOL monitoring.

Selectable Zonal or General
Alarm Sounder operation
9.8
The Zonal Alarms DIL switch allows the sounder
circuits to operate zonally in line with the zone in
alarm. The actual operation of the alarm circuits will
vary depending on the type of zone detection and
number of zones available on the panel.
Twin-wire panels (1 to 8 zone):
All twin-wire sounders operate zonally, sounder
circuits on the motherboard operate as general
alarms (i.e. all four alarm circuits on the
motherboard operate for any zone fire)
Standard panels, 1 to 4 zone panels:
Sounder circuits 1 to 4 operate individually for a
fire condition on the respective zone.
Standard panels, 8-zone panel:
Sounder circuits 1 to 4 operate as general
alarms (i.e. all four alarm circuits on the
motherboard operate for any zone fire). Zonal
sounder operation is not available.
9.7
Buzzer Disable
The DISABLE BUZ DIL switch allows the panel
buzzer and Buzzer Active output to be disabled so
tat they do not operate for alarms or faults. The
panel buzzer will still operate for button presses.
The panel does not give any indication that the
buzzer has been disabled. This feature is
provided for use during panel commissioning
and maintenance only. Ensure that the DIL
switch is returned to the OFF position after
commissioning/maintenance
tests
are
complete.
Earth Fault monitoring.
The DUO-CEL panel is designed to monitor for low
impedance faults to earth on the field cables. Earth
faults can lead to false alarms or failure to operate
the sounders or other outputs.
For installations where earth fault monitoring is
unsuitable, it can be disabled by removal of the
insulated jumper link (see Figure 3). The link can be
rotated and placed just on one pin rather than
across both pins. This should be done only after
all field cabling has been tested and confirmed
to be free from faults.
10. Panel Repeaters
The DUO-CEL repeaters duplicate the panel
indications and main user controls at a location
remote from the main panel. The repeater uses the
same enclosure & control board as the fire alarm
panel although most of the components are
depopulated from the control board. Up to 3
repeaters can be connected to a single panel using
an RS485 serial connection.
Each repeater can be powered either from the
Auxiliary 24Vdc output of the panel or an internal
power supply (optional).
Note:
The disable/enable/test facilities and the
configuration functions are not available at the
repeaters.
Repeaters cannot be used with the 1 & 2 zone
panels.

varies with temperature and during mains-failed
conditions, depending on battery voltage. See
section 14 for details of maximum load.
The output is fused using an electronic device, and
fuse activation will be indicated as Fuse Failed on
the panel display. The fuse can be reset after
clearing the fault by operating the Reset button on
the display.
The auxiliary supply terminals are labelled Aux
0.25A 24V and 0V.
An additional UNFUSED 24V output is provided on
repeaters for connection to additional DC powered
repeaters.
Note: If equipment draws current from the

Fire Relay Output
The Fire Relay output is a single pole relay with
volt-free change over contacts. The relay is
normally de-energised and energises for any fire
alarm condition. The relay remains energised until
panel reset. This relay will not energise if zone 1 is
configured as non-latching and only zone 1 is in
alarm. See Figure 9 for details.
11.6
Fault Relay Output
The Fault Relay output is a single pole relay with
volt-free change over contacts. The relay is fail-safe
and is therefore normally energised, de-energising
for any faults. The marking on the control board
terminals is for the energised condition. See Figure
9 for details.
NOTE:
The volt-free relay contacts are rated at 30Vdc
with a maximum current of 1A. Do not exceed
the rated voltage and current.

Note:
To prevent unauthorised operation of the
system, any manually operated function must
be operated by a key-switch. The key to the
switch should be held with the panel’s access
control key.
For the SILENCE ALARMS and RESET
functions, the Keyswitch should be springbiased so that it automatically returns to the off

They are referred to as „open collector‟ because
each output is connected to the open collector pin
of a transistor.
In the deactivated state, each open collector output
is floating and is effectively open circuit. When the
output is activated, the transistor allows current to
flow from the open collector pin down to 0V. Each
output is able to sink 50mA when active. Higher
currents will damage the transistor driver.
If the output is used to drive a relay then a
suppression diode should be used across the relay
coil to avoid damaging the output driver circuit.
11.8.1 Disabled Output
The Disabled output is activated when any
disablements exist on the panel. The only
exceptions are Buzzer Disable and Earth Fault
Disable, both of which produce no indications on
the panel.
11.8.2 Evacuate Output
The Evacuate output is activated when the panel is
in the Evacuate state, either due to the button on
the display or due to the Remote Control input.
the end of each circuit exceeds the minimum
required by each sounding device.
The voltage at the end of the circuit is given by the
following calculation:
Valmin = Vopmin – (Ial x 2 x Lal x Rcable)
Valmin = Minimum Alarm Voltage (V)
Vopmin = Minimum Output Voltage (19.5V)
Ial = Alarm Current (A)
Lal = Alarm Circuit length (M)

11.10 Electrical Design of Detection
Zones
To allow the panel to correctly monitor for fault
conditions, the wiring for each zone must be
installed as a continuous pair with no spurs or tees.
The end-of-line monitoring device will depend on
the type of panel. Correct polarity must be strictly
observed throughout.
11.8.3 Buzzer Active Output
11.10.1 Standard Panel Default Zone
Configuration
The Buzzer Active output duplicates the panel
buzzer for alarm and fault conditions. It does not
operate for button presses.
The standard panel zone configuration (factory
Default) uses active fault monitoring, with a 10uF
capacitor as the EOL device (see Figure 13).
11.9
11.10.2 Standard Panel Resistor Zone
Configuration
Sounder Circuits
The DUO-CEL panel has up to 4 standard sounder
circuits, each rated at 0.5 Amps (not including twinwire sounders). The circuits are reverse polarity
monitored for open and short circuit faults. All
connected field devices must be polarised to allow
correct fault monitoring. To prevent damage to the
control panel, any solenoid devices such as bells
must also have a suppression diode fitted as shown
in Figure 11.
The circuit must be terminated with a 10K end of
line resistor.

The standard panel can be set to resistor zone
configuration (set by DIL switch). This uses passive
fault monitoring, with a 6K8 to 3K9 resistor as the
EOL device (see Figure 14).
11.10.3 Twin-Wire Panel
The Twin-Wire panel uses passive fault monitoring
but with an EOL device consisting of a zener diode
and resistor as shown in Figure 12. The device is
polarised and should not be connected in reverse
(otherwise the panel will indicate an alarm
condition). This EOL device allows monitoring for
detector head removal whilst maintaining line
continuity via diodes fitted to detector bases.
The addition of the zener and resistor enables the
twin-wire sounders to operate, even with one
detector removed.
Only use detector bases with line continuity diodes
fitted.
DO NOT leave any diode bases empty. Detectors
should be fitted or a blanking plate which links out
the diode should be fitted.
NOTE: The twin-wire EOL will draw up to 4mA from
the zone in quiescent and this should therefore be
added to the total zone current when calculating the
standby battery requirements.
The voltage drop on each alarm circuit should be
calculated to ensure that the minimum voltage at

11.10.4 Maximum Number of
Detectors/MCPs on a Zone
For the standard panel with 10uF EOL capacitor,
the maximum number of detectors & MCPs per
zone is limited to 32.
For the standard panel with EOL resistor, the
maximum number of devices allowed on a zone is
limited by the quiescent current drawn by each
device. The quiescent current will be listed on the
device data sheet provided by the Manufacturer of
the device. See section 7.1 for details.
The maximum quiescent current available to power
devices on a zone is 1.6mA. Exceeding this value
will prevent the panel from correctly monitoring for
open circuit fault conditions.
For the Twin-Wire panel the maximum number of
detectors & MCPs per zone is limited to 16 (or less,
see section 7.1) if sounders are also connected. If
no twin-wire sounders are on the zone then up to
30 detectors & MCPs may be connected (see
section 7.1 for details). The maximum number of
twin-wire sounders permitted is 12 (or less; see
section 7.1).
Note: It is a recommendation of BSEN 54-2 that
there should be no more than 32 detectors &
MCPs in a zone.

11.11 Panel to Repeater Wiring
The Repeater RS485 communication and 24Vdc
power connections should all be made via a single
multi-core data cable. The number of cores
required is two if the repeater is mains powered, or
four if powered from the panel. A cable screen is
not required but is usually present in most data
cable types. The A & B lines should be connected
via one set of twisted pair cores, the 24V & 0V lines
should be connected via another set of twisted pair
cores.
If the cable includes a screen then this should be
earthed at the panel & all repeaters.
Terminal A at the panel must be connected to
Terminal A at all repeaters, Terminal B at the panel
must be connected to Terminal B at all repeaters.

Safe State
The microcontroller in the DUO-CEL panel
continuously monitors the firmware memory,
the volatile memory and the configuration
memory for corruption. If an error is detected,
the software enters the safe state. In addition,
a hardware circuit monitors the microcontroller
for correct operation. This hardware watchdog
circuit will also place the panel in the safe state
if the microcontroller fails to work correctly.
In the safe state, all outputs are deactivated
and only the SUPPLY ON, GENERAL FAULT
& SYSTEM FAULT LEDs are illuminated. The
buzzer will sound continuously.
